Attention should be paid to trademark registration: the applicant for trademark registration applies, and the Trademark Office will make a preliminary examination and announcement after examination. If no objection is raised within three months or the objection is ruled invalid, the trademark will take effect and be protected by law, and the trademark registrant will enjoy the exclusive right to use the trademark. It takes more than one and a half years to apply for trademark registration. There is no statutory time limit for the approval or rejection of an application for trademark registration. At present, the trademark is announced in the first instance about two years from the date of application (earlier if rejected). If there is no objection to the trademark within three months from the date of the announcement of the first instance, the Trademark Office will make an announcement on the examination and approval of the trademark, and then issue a trademark registration certificate, and the trademark will be approved. The time period of trademark examination will change at any time according to the speed of internal examination of the Trademark Office. The period of validity of a registered trademark is 10 years, counting from the date of approval of registration. If the registered trademark expires and you want to continue to use it, you can apply for trademark renewal.
